Small Bodies Near and Far (SBNAF): A benchmark study on physical and thermal properties of small bodies in the Solar System
Marton, G.; Müller, T. G.; Alí-Lagoa, V. +15 more
The combination of visible and thermal data from the ground and astrophysics space missions is key to improving the scientific understanding of near-Earth, main-belt, trojans, centaurs, and trans-Neptunian objects. To get full information on a small sample of selected bodies we combine different methods and techniques: lightcurve inversion, stella…
Infrared studies of molecular shocks in the supernova remnant HB 21: II. Thermal admixture of shocked H2 gas in the south
Koo, Bon-Chul; Lee, Ho-Gyu; Moon, Dae-Sik +2 more
We present near- and mid-infrared observations on the shock-cloud interaction region in the southern part of the supernova remnant HB 21, performed with the InfraRed Camera (IRC) aboard AKARI satellite and the Wide InfraRed Camera (WIRC) at the Palomar 5 m telescope. The IRC 4 µm (N4), 7 µm (S7), and 11 µm (S11) band images and t…
AKARI observations of the ISM in our Galaxy and nearby galaxies
Takahashi, H.; Onaka, T.; Kaneda, H. +1 more
With AKARI, we have systematically performed near- to far-infrared (NIR-FIR) observations of the interstellar medium (ISM) in our Galaxy and nearby galaxies as one of AKARI mission programs called ISMGN (ISM in our Galaxy and Nearby galaxies). Our scientific objective is to increase our knowledge on the properties of the ISM exposed to an extensiv…
Galaxy colours in the AKARI deep SEP survey
Nakagawa, Takao; Shirahata, Mai; Jeong, Woong-Seob +7 more
We investigate the segregation of the extragalactic population via colour criteria to produce an efficient and inexpensive methodology to select specific source populations as a function of far-infrared flux. Combining galaxy evolution scenarios and a detailed spectral library of galaxies, we produce simulated catalogues incorporating segregation …
AKARI (ASTRO-F): Flight performance and preliminary results
Shibai, Hiroshi
ASTRO-F, which is the first Japanese satellite mission dedicated to the infrared wavelength region, was successfully launched on February 21, 2006 (UT), and was named "AKARI". The telescope has a 69 cm aperture, and is cooled to 6 K with super-fluid helium and mechanical coolers. AKARI is designed for the most advanced all-sky survey in the mid- a…
Detection of CFIRB with AKARI/FIS deep observations
Nakagawa, Takao; Shirahata, Mai; Jeong, Woong-Seob +8 more
The Cosmic Far-Infrared Background (CFIRB) contains information about the number and distribution of contributing sources and thus gives us an important key to understand the evolution of galaxies. Using a confusion study to set a fundamental limit to the observations, we investigate the potential to explore the CFIRB with AKARI/FIS deep observati…
